From the Low Temperature Lab: A flux-pinning enhanced superconducting puck levitates above and is pinned to a magnetic figure-8 track. This demonstrates the quantum physical effect of superconductivity and the Meissner Effect as well as magnetic flux pinning. The puck is accelerated using the motors from a toy car track set.
